Floodbase API Aims to Digitize and Scale U.S. Flood Insurance

NEW YORK, NY – March 05, 2026 – Insurtech firm Floodbase today unveiled a new technology platform designed to overhaul the slow and complex process of securing flood insurance, aiming to close a critical protection gap for thousands of American businesses. The company's new Floodbase Quote API enables insurers to generate quotes for parametric flood coverage in minutes, collapsing a manual process that has historically taken weeks and left many small and mid-sized companies exposed to catastrophic financial loss.

The launch represents a significant step toward automating a historically bespoke corner of the insurance market. By providing instant, data-driven pricing information, the platform seeks to empower insurers and brokers to distribute flood protection products at a scale previously thought unattainable, particularly within the vast and underserved small to mid-sized commercial sector.

Dismantling a Manual Bottleneck

For years, the process of obtaining parametric flood insurance—a type of coverage that pays out a predetermined amount based on a specific event trigger, such as floodwater reaching a certain depth—has been a significant barrier to its widespread adoption. The manual nature of quoting required underwriters to conduct location-by-location analysis, a bespoke and time-consuming effort that restricted their capacity and made it unfeasible to service smaller clients.

This lengthy submission-to-quote cycle meant brokers could not efficiently secure options for their entire client base, leaving significant value on the table. Consequently, businesses remained vulnerable, brokers were unable to service their complete books, and insurance carriers missed out on substantial untapped premium.

Floodbase's new API directly confronts this inefficiency. It is built to enable automatic or self-serve workflows, instantly returning the necessary data to price a standard parametric flood cover for a single location. For a given address, the API generates a localized daily flood history spanning nearly five decades. This instant delivery of critical data allows underwriters to apply predefined rules or integrate their own pricing models to generate quotes with minimal manual intervention.

"This is a true unlock," said Annbjørg Medhaug, Chief Product Officer at Floodbase, in a statement. "We're dismantling structural barriers that have prevented brokers and carriers from serving everyone in the U.S. flood market with scalable parametric flood products."

A Lifeline for Underserved Businesses

The impact of this technological shift is aimed squarely at one of the nation's most pressing insurance challenges: the flood protection gap. Flooding is the most common and costly natural disaster in the United States, yet a staggering two-thirds of modeled U.S. flood losses go uninsured, according to industry reports. While large corporations may have the resources to secure complex insurance solutions, small and medium-sized businesses (SMBs) are often left behind.

Most standard business insurance policies do not cover flood damage, forcing business owners to seek separate, often expensive and complicated, coverage. The new automated quoting process makes it viable for insurers to target the high-volume SMB market where speed and standardization are essential. By reducing the administrative burden, the technology lowers the barrier for brokers to proactively offer flood solutions to clients who may have previously overlooked the risk.

This expansion of access comes at a critical time. With U.S. flood damage estimated to cost the economy between $180 billion and $496 billion annually, providing a financial backstop for smaller enterprises is crucial for community resilience. Faster, more accessible insurance can mean the difference between a business reopening quickly after a flood or closing its doors for good.

Parametric Power in Practice: The Liberty Mutual Partnership

The potential of this new technology is already being realized. Liberty Mutual Re, the reinsurance arm of the global insurer, recently announced the launch of an instant large-area parametric flood quoting application for brokers, powered directly by the Floodbase API. This partnership serves as a powerful proof of concept, demonstrating how the platform can be integrated by major carriers to revolutionize distribution.

The Liberty Mutual application allows brokers to price parametric flood covers in minutes, a dramatic acceleration of the traditional process. The solution offers up to $25 million in limits for a single location, with significantly higher limits available for portfolios covering multiple locations. This move signals a strategic shift toward making parametric solutions a mainstream, easily transactable product rather than a niche, complex placement.

By equipping its distribution partners with this tool, Liberty Mutual aims to respond more quickly to submissions and provide more adaptable solutions in the face of evolving flood risks. The collaboration underscores a broader industry trend toward leveraging technology to make insurance products faster, smarter, and more accessible to those who need them most.

The Science Behind the Speed

The engine driving this innovation is Floodbase's sophisticated data infrastructure, built on more than a decade of scientific and engineering work. The platform's ability to generate instant quotes is not just a matter of software automation; it is rooted in a deep well of climate and hydrological data.

The company's modeling infrastructure continuously maps and calibrates floods across the United States, integrating data from seventeen different observational sources, including advanced satellite imagery and a network of national stream gauges. This multi-source approach allows for consistent and scalable flood monitoring, even overcoming common challenges like cloud cover. By feeding this near real-time intelligence into models trained on nearly 50 years of historical flood data, the platform can generate highly localized and scientifically credible risk assessments instantly.

"The Quote API is built on Floodbase's scientifically rigorous flood modelling infrastructure," noted Subit Chakrabarti, the company's Chief Technology Officer. "By delivering location-specific flood intelligence instantly and at scale, we are transforming how parametric flood can be structured and deployed in the U.S. market." This scientific underpinning is crucial for the trust of re/insurers like Swiss Re and AXA Climate, who also partner with the firm.

Navigating a Shifting Regulatory and Climatic Landscape

Floodbase's innovation arrives as both climatic and regulatory landscapes are shifting. The increasing frequency and intensity of extreme weather events have made scalable risk transfer solutions more urgent than ever. Parametric insurance is increasingly seen as a vital tool for climate adaptation, offering rapid payouts that can fund immediate recovery efforts without the lengthy claims adjustment process of traditional indemnity policies.

Simultaneously, the regulatory environment is beginning to evolve. While the federally backed National Flood Insurance Program (NFIP) remains a cornerstone of U.S. flood coverage, private market solutions are gaining traction as a necessary complement. States are taking notice. New York, for example, recently passed its first parametric insurance law, which will take effect in 2025, formally recognizing it as an authorized form of insurance while requiring clear disclosures that it is not a full substitute for traditional property coverage.

This growing regulatory acceptance, combined with powerful new enabling technologies like the Floodbase API, is paving the way for a more resilient future. By making parametric flood insurance easier to quote, position, and transact, the industry can begin to meaningfully address the vast and dangerous flood protection gap facing the nation.
